I've stumbled upon the viewing.nyc article Upper West Side Has Its Own Ant Species Dubbed the "ManhattAnt" which says:
Columbia University biologist Rob Dunn has discovered a unique species of ant living between 63rd and 76th streets along Broadway on the Upper West Side of Manhattan. Dubbed the "ManhattAnt", the ants have a higher concentration of carbon in their bodies, indicative of a high corn-syrup diet, likely from eating trash and discarded street food.
Biologists stumbled upon a new species of ant in the Broadway medians at 63rd and 76th streets […] The ant looks like it hails from Europe, but so far the scientists have not been able to match it with any of the approximately 13,000 species of known ant. “It’s new to North America, and we believe it’s new to the entire world,” biologist Rob Dunn, whose team discovered the insect, told the Post. The ant doesn’t have a scientific name yet, but it’s fondly nicknamed the “ManhattAnt.”
and references the Simthsonian Magazine article NYC Has Its Own Ant, the “ManhattAnt” with the subtitle:
A new ant species joins a menagerie of other creatures cut off from their kind in isolated patches of urban green in NYC
A "new species" is not the same thing as a "creatures cut off from their kind in isolated patches of urban green in NYC"
Question: Has the "Manhattan Ant" or "ManhattAnt" turned out to be a new species, and is it still only found in Manhattan's Upper West Side?
